自2005年以来,REDD+项目在巴西等热带地区得到了广泛地计划和实施。然而,在后京都时代全球背景下,只有拓宽REDD+机制的实施途径才能在所有森林覆盖的国家起到减排作用,这也为中国提供了参与减排的重要机会。积极参与REDD+机制,不仅有利于进一步开发我国碳汇潜力,更有利于提高我国在国际气候谈判中的地位、掌握碳交易市场的话语权。将菲律宾作为REDD+在新兴国家发展的典型案例,进行REDD+机制在中国扩大途径研究,构建中国REDD+机制多元化框架,同时为REDD+在中国的发展提出可行性的政策建议。 相似文献

以转基因技术为代表的现代农业生物科技正面临两难发展困境,公众在对待农业生物科技的发展和选择上常常存在误判,主要表现在:对农业生物科技起源及进化的误识、对技术内涵及术语的误读、对技术风险属性的误解以及对技术路径选择的误判等,政府决策也因此而陷入二难困境。要破解这种认识与发展困境,可以从公众科学素养培育、科技术语表述分析、多元化信息交流、技术风险与利益测评等方面综合寻求解决之道。 相似文献

This paper builds on social network theory to understand technological development. Based on the empirical evidence of 367 research organisations in plant biotechnology over a nineteen-year period, we demonstrate how a structural analysis of the research network within the technological community is used to identify four collaboration-based strategic groups of research organisations. The emergence of these groups can be linked to technological breakthroughs in the field. Analyses of the four clusters point to the influence of research collaborations on stratification within an evolving technological domain. Finally, as archival data sources are used to detect incidences of collaborative research and to trace the evolution of R&D networks in an emerging field, we conclude with a discussion of the potential contribution of bibliometric data to understand the development of new technologies in their early, pre-commercial phases. 相似文献

During the last two decades, policymakers in various positions have been adopting a systems-approach to policy thinking. However, in contrast with the quasi-evolutionary way in which policy is thought of and conceptualised it seems that policy doing is still being guided by ‘market-failure’ justifications causing actual policies to remain narrow in their scope. In this paper we sidestep this analytical divide of thinking/doing by developing a co-evolutionary framework that utilises a more productive analytical divide of means/ends. That is to say we focus on a process of co-evolution of a higher-order, one which takes place ‘inside’ the agent of policy herself, and involves changes in the ways ‘means’ and ‘ends’ are understood and acted upon. Conceptualising policy problems in terms of means/ends contributes to current debates by rendering the difficulty that countries are facing in their attempts to prioritise biotechnology more intelligible and thus manageable. 相似文献

Reducing Emissions from Deforestation and forest Degradation (REDD+) is critical in efforts to mitigate the effects of anthropogenic climate change. Despite uncertainty about the exact form of a future, international REDD+ system, REDD+ carbon property rights would need to be created and allocated with liability assigned for the potential loss of climate benefits in the event of carbon reversal from deforestation. This commentary explores the links between forest property rights and liability, to different REDD+ policy options and their implications for permanence. Should national governments retain liability for permanence then project-level activities that have individually-assigned REDD+ carbon rights may have a higher risk of carbon reversal than policies where rights are assigned to the state. Knowledge of pre-existing forest rights is necessary for some policies implemented with government-assigned REDD+ rights in order to compensate for potential income losses from policy implementation. 相似文献

The ‘life science’ revolution related to the development of biotechnology affects many different markets. In the pharmaceutical business new drugs are continuously developed, tested, and submitted to governmental institutions for the required approval. In the agricultural business the so-called ‘green revolution’ is well under way with many new products designed in order to appeal to farmers or to consumers. The increasing pace of introduction of new biotech products—particularly drugs and agrochemical (Ag) foods—leads firms to look for collaborations in the different phases of the introduction process. Basing on an empirical study conducted on a sample of 27 organisations involved in the process of introduction of biotech products, the paper aims at comparing and contrasting the nature and the processes involved in inter-institutional collaborations occurring at various stages of new product development and commercialisation of new biotech products (particularly drugs and Ag foods). 相似文献

We examine the causation and effectuation logics for implementing targeted biotechnology policies using two case studies: Singapore (causation) and Israel (effectuation). After more than a decade of implementing targeted biotechnology policies, both Singapore and Israel have failed to create fully fledged biotech clusters. Singapore has been unsuccessful in creating vibrant entrepreneurial activity that will support its transformation into a knowledge economy. Israel has failed to turn its 1000 small, dedicated biotechnology firms into a substantial engine of growth and employment. The paper questions how these two policy approaches influenced the targeting of the biotechnology sectors and identifies the limits of these approaches in supporting targeting. We conclude that a combination of the two logics is needed, especially when targeting complex sectors with a yet unknown development path. 相似文献

We propose the use of machine learning methods to estimate inequality of opportunity and to illustrate that regression trees and forests represent a substantial improvement over existing approaches: they reduce the risk of ad hoc model selection and trade off upward and downward bias in inequality of opportunity estimates. The advantages of regression trees and forests are illustrated by an empirical application for a cross-section of 31 European countries. We show that arbitrary model selection might lead to significant biases in inequality of opportunity estimates relative to our preferred method. These biases are reflected in both point estimates and country rankings. 相似文献

This paper presents economic rules for harvest timing when timber and nontimber goods, services, and ecological functions
are produced from forest stands. Forests include stands that are heterogeneous in age, land quality, and distance to market.
Rules for allocating land between forest and nonforest use are developed. Key land use margins are identified that are important
to land use allocation in temperate and tropical regions (e.g., between unmanaged forest, forest management, and forest conversion).
Processes that can change key land use margins are discussed and used to organize recent empirical and theoretical studies
of regions where forest land use is in transition, such as where forest land is being converted to alternative nonforest land
uses. 相似文献

采用比较分析法和数据包络分析法(DEA),分析了劳动力迁移、人力资本与农业技术进步之间的关系。认为劳动力迁移有利于劳动力人力资本水平的提高;农业技术效率在短期内受到物质资本投入、劳动力素质等因素的强性约束。长期来看,约束因子会不断放松;劳动力迁移对迁入地的农业技术进步是有贡献的。 相似文献
